Magnum MS 2812 Not Working Properly Fault code

So Today I fixed a Magnum MS2812 It Was in a Fault code lock out. So Customer said it showed 135 for the fault code. I talked to magnum Energy Tech Support because I have never heard of such a code. He informed me that it was internal data and that I should not be seeing it. So he then told me how to fix it. Here is how I did it..

Step 1 make sure you are on DC power only.

step 2 Remove controller from wall

step 3 Unplug the data cable from the controller.

step 4 on the Inverter there is a power button Hold it till the green light flashes rapidly then release

step 5 Inverter should be off because it Reset itself.

Step 6 go inside the coach and plug the controller back in

step 7 turn the inverter on

step 8 check to see if the unit is working and no longer in fault mode..

step 9 your done if it is working..

Note if your still having the same error you can hard reset your inverter by unhooking the 12 volt dc and waiting for 10 minutes. make sure everything is unplugged when you do this including the shore power the controller and all inverter's should be off.
